nlp-'s Introduction

NLP-知识

(1)word2vec

优化方法:

为了提高速度,Word2vec 经常采用 2 种加速方式:Negative Sample(负采样),Hierarchical Softmax

缺点:

(1)由于词和向量是一对一的关系,所以多义词的问题无法解决。
(2)Word2vec 是一种静态的方式,虽然通用性强,但是无法针对特定任务做动态优化

优点

(1)由于 Word2vec 会考虑上下文,跟之前的 Embedding 方法相比,效果要更好(但不如 18 年之后的方法)
(2)比之前的 Embedding方 法维度更少,所以速度更快
(3)通用性很强,可以用在各种 NLP 任务中
